3D printing is also known as additive manufacturing. 3D printer is used to create three dimensional objects irrespective of size and shape from a digital model. Rapid prototyping is one of the applications of 3D printer. Industrial 3D printer is used widely for research purposes. They are normally larger machines that make use of casting media, proprietary powdered metals, papers, plastic or cartridges and commercial companies.
3D printing has recently entered the field of rapid manufacturing and experts discovered that it as “next level” technology in 2009. It is used to adapt selective laser sintering or direct metal laser sintering. Few well established rapid prototyping methods are also used along with those technologies. It has got lot of obstacles that has to overcome before the introduction of RM then it could have been considered as realistic manufacturing method.
Certain services allow the consumers to customize objects with the help of simplified web based customization software. They can also order items as 3D printed unique objects. Custom cases can be created by the consumers to their cell phones.
The present speed of the 3D printers limits their utilization for mass production. To overcome this limitation many fused filament machines provide multiple extruder heads. This helps to print several colors with various polymers. Multiple prints can also be done simultaneously. This results in increasing the overall speed of the printer. Nowadays, maximum printers come with twin print heads. It is mainly used to manufacture single piece in multiple materials/colors.
